Another embodiment of the present invention relates to a kind of rotary filter (including, but not limited to metal rotary filter, composite rotary filter, the perhaps rotary filter of making by other material), a kind of cut-off valve (including, but not limited to following drop valve or spring valve) and a kind of filter.Described rotary filter projection, this projection is stretched out the top face at packing ring, and is used to open the liquid communication passage of described valve in the filter.When the compatible filter that comprises described projection and described filter were assembled together, described valve was pushed up, and described circulation passage is opened.When incompatibility filter and filter were assembled together, described circulation passage kept closing (according to the type of used valve, making circulation passage keep closing by stream power or spring).

Term " compatible filter " repeatedly uses in this article.It will be appreciated that, here said compatible filter is not meant that this device is flexible, and being meant so a kind of filter: this filter has one or more features, such as having engaging mechanism, when this engaging mechanism and filter are assembled together, can make by the circulation passage of the valve in the filter and open.That is to say, use the incompatibility filter can cause blocking, flowing by the valve in the filter can not taken place this moment.In other words, when not using compatible filter, will there be fluid (as fuel) to flow through the interior valve of filter.

The many aspects of an embodiment of valve of the present invention have been showed in Fig. 1～4.Valve in Fig. 1～4 is a cut-off valve, is suitable for using in the filter of internal combustion engine.Described cut-off valve 100 extends between first terminal 120 and second end 130.First end 120 is also sometimes referred to as top 120, the second ends 130 and is also sometimes referred to as bottom 130.Fig. 1 and 3 has showed the cut-off valve 100 when being in the running status or first mode.Similarly, Fig. 2 and 4 has showed the cut-off valve 100 when being in the blocked state or second mode.In running status, shown in flow arrow among the figure 105,106,107,108 and 109, fluid enters the top 120 of valve 100, and described fluid is before flowing out second end 130 shown in flow arrow 109, substantially in the internal flow of valve 100.Cut-off valve 100 preferably and spring 110 be used, described spring 110 is maintained in the filter between first area and the second area 140, described first area is defined in the inlet of filter (not shown in Fig. 1～4), and 140 parts by cut-off valve 100 of described second area define.

Between first terminal 120 and second end 130 of described valve 100, have outer surface 103 and inner surface 104.Described inner surface 104 has defined the first passage between the end face 124 of first end 120 and inner spoiler 125.Inwall 104 has defined the second channel between the bottom surface 126 of spoiler 125 and second end 130.Valve 100 comprises a plurality of first openings 145 that are defined between outer surface 103 and the inner surface 104.Similarly, valve 100 also comprises a plurality of second apertures between outer wall 103 and the inwall 104.Described a plurality of first opening 145 is between first end 120 and spoiler 125.Described a plurality of second aperture 155 is between the inner spoiler 125 and second end 130.Preferably, valve 100 also comprises outside O shape ring 150, and this outside O shape ring 150 is set between described a plurality of first opening 145 and described a plurality of second aperture 155.As more specifically described as the following, when described valve is in second mode (being also referred to as blocked state), described outside O shape ring 150 parts as the circulation passage closing organ.

Second end 130 of valve 100 comprises annular section 132 and zone 134.In first mode of valve work, described valve allows fluid to flow to second end 130 from first end 120, shown in flow arrow 105～109.Fluid enter first end 120 (arrow 105) and pass 104 that define by inner surface, first terminal 120 and inner spoiler 125 between first passage.Then, fluid is discharged (shown in arrow 106) by described a plurality of first openings 145.At first operation mode, when circulation passage is opened, (be also referred to as running status), the bottom surface 194 of the fixator part 190 of described valve and bottom 130 described regional 134 adjacent substantially.When described fixator part 190 is provided with like this, flow back into the inside (shown in arrow 107 and 108) of valve 100 by described a plurality of second apertures 155 from the fluid of described a plurality of first openings 145 discharges.Then, fluid 126 places, bottom surface of spoiler 125 internally begins to flow, flows through the second channel that the inner surface 104 by valve 100 defines, and discharges (shown in arrow 109) from second terminal 130 again.Therefore, in first mode, flow in the fluid valve 100 between first terminal 120 and second end 130 on the throne substantially.

In one embodiment, valve 100 can have impact property (impactor capability).As mentioned above, in running status, fluid be downward through valve 100 centre gangway, by opening 145 from described centre gangway discharge, again by opening 155 reenter described centre gangway, then along centre gangway continue to dirty, up to dump valve 100.For impact property is provided, can when leaving centre gangway, fluid quicken by convection cell.Fluid after the acceleration can impact a surface in outlet opening 145 back, for example shell wall or in order to make the more convenient and surface that is provided with of impact.Impact can remove degranulation, for example solid particle or drop from fluid.Now existing a lot of technology can provide the fluid that is suitable for impacting to quicken, and for example, increase or reduce the size of opening 145 and/or 155, add a plate or other structure above O shape ring 150, but perhaps adopt other operating technology that accelerating fluid is provided.One is utilized the embodiment of impact property is the crankcase ventilation accelerator.Impact property also can provide with other embodiment.

As previously mentioned, Fig. 2 and 4 has showed cut-off valve 100, and this cut-off valve 100 is in second mode or the state, and at this moment, the fluid stream that enters first end 120 is not substantially in the internal flow of valve 100, to discharge by second end or bottom 130.Otherwise in second mode, fixator part 190 (can move with respect to the outer surface 103 of valve 100) is arranged on the position of contiguous outside O shape ring 150.Therefore, the fluid of discharging from described a plurality of first openings 145 is bottled up by door (end face 192 by fixator 190 and O shape ring 150 constitutes), can not arrive described a plurality of second aperture 155.In second mode, the bottom surface of the fixator part 190 of valve 100 194 and the zone 134 that is positioned at 130 places, the valve 100 bottoms segment distance of being separated by.The fixator part 190 of valve 100 is fixed on the position in the filter, and the other parts of valve move with respect to fixator 190.Especially, shown in Fig. 1～4, fixator part 190 comprises outer circumferential surface 196, defines fluted on this surface 196 or caves in 198.Be placed with snap ring 195 in the depression 198, the size and dimension of this snap ring 195 is suitable for locking in the interior respective recesses of filter.

Fig. 5 and 6 has showed an embodiment of mounted valve, wherein, does not have compatible filter among Fig. 5, has compatible filter among Fig. 6.Valve 200 is a fuel control valve.Fuel control valve 200 extends between first terminal 220 and second end or the bottom 230.Valve 200 to small part is arranged in the inlet duct (figure is not completely shown) of the filter with first pipe section 302 and second pipe section 303.Different-diameter between described inlet duct first 302 and the second portion 303 has defined first area 306, and this first area 306 engages with spring 210.Spring 210 extend first area 306 that the inlet duct by filter 300 (see figure 9)s defines and the second area 240 that defines by the part of valve 200 between.

The parts in the internal volume 212 of fuel control valve 200 have been saved in the accompanying drawing, because these parts are helpless to understand the present invention.When compatible filter was installed, described compatible filter engaged with the bottom 230 of control valve 200, and compression spring 210.When spring 210 is compressed, be forced to flow through the internal volume 212 of fuel control valve 200 from the fuel of the inlet duct 302 of filter 300.When lacking compatible filter, bottom 230 breaks away from the fixator part 290 of fuel control valve 200 under the effect of spring 210.Fixator part 290 is similar to the fixator part 190 of fuel cut-off valve 100.Fixator part 290 has snap ring 295, and this snap ring 295 is installed in the respective recesses of filter 300 (see Fig. 7 and 8, hereinafter will describe in detail).

As shown in Figure 5, when lacking suitable filter, control valve 200 is remained on common open position by spring 210, and described spring 210 makes valve 200 break away from valve seat, and fuel or other fluid are walked around from the next door of control valve.As shown in Figure 5,201 places walk around control valve 200, flow in the outside 203 of valve 200 in the position from the fuel of inlet duct 302 or other fluid, and the second portion 303 of inlet duct flows out at 202 places in the position.202 fuel that flow out are then walked around the other parts of described valve by flowing through each opening 206 from the position.
